One of mine is the Allium Gladiator! 
The bulbs are preferably planted in clumps of 10 or more during fall and will bloom during late spring into early summer. They really give you a stunning look in your latespring garden. The flowers will grow to a ‘globe’ of around 6 diameter with a sweet scent to it! I like flowers to stay as they are in the garden, however they are also good as cut flowers or in dried flower arrangements.
